Question

Write a class that has three overloaded methods for calculating the areas of the following geometric shapes:

 

•    Circle

•    Rectangle

•    Cylinder 

Answer 1

class Shape {


	public double calculateArea(double radius) {
		return Math.PI * radius * radius;
	}


	public double calculateArea(double width, double height) {
		return width * height;
	}


	public double calculateArea(double radius, double height, int k) {
		return 2 * Math.PI * radius * (radius + height);
	}


}


class App {


	public static void main(String[] args) {
		Shape s = new Shape();


		System.out.println("The area of circle is: " + s.calculateArea(5));
		System.out.println("The area of rectangle is: " + s.calculateArea(5, 4));
		System.out.println("The area of cylinder is: " + s.calculateArea(5, 4, 5));


	}
